AXLE-BOX LID.

SPECIFICATION forming part of Letters Patent No. 588,960, dated August31, 1897. Application filed December 29, 1893. Serial No. 495,073. (Nomodel.)

To all whom it may concern.-

Be it known that I, NATHAN I-I. DAVIS, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, in the has forits object to provide a new and useful device for anchoring the springto the lid.

My invention will be best understood as explained in connection'with theaccompanying drawings, in which-- Figure 1 is a perspective view of anaxlebox having an outwardly-opening lid. Fig. 2 is a section on the line00 a: of Fig.1, showing the spring for holding the lid to the face ofthe box and the socket for securing the spring to the lid. v Fig. 3 is aperspective view of my improved socket, and Fig. A is a perspective viewof a modified socket-piece.

A is an axle-box, the box A, as shown in Fig. 1, being provided with alid B, which opens outwardly and which, as shown, is pivoted to the boxbya bolt a,which engages with the pivot-eyes b on the lid and with a camshoulder O on the box.

D is a socket having a recess d, in which the end of the spring isadapted to engage, and this socket is secured to the inner face of thelid by a flat heel extension, as shown, and by rivets e, passing throughthe same.

In order to prevent longitudinal movement of the spring after it is inposition, which would result in its disengaging itself from its socket,I form the spring S with a turned-over end 8 and form the recess d bybending up the end 01' of the socket, as shown in Fig. 3, so that whenthe spring is in place, as shown in Fig. 2, the end'of the spring willengage with the recess d, and the end (1 will prevent longitudinalmovement of said spring.

To prevent lateral movement, a recess or depression 19 is pressed orotherwise formed in the lid," the sides I) of which serve asshoulders,which abut against the sides of the spring when it is inposition. Abutting-shoulders may be formed also on the socket D, asindicated at 1 Fig. A.

In the construction described it will be noted that the spring isentirely within the box, and there are no holes or openings in the lidfor the entrance of dirt and dust,and a new spring can readily andeasily be substituted for an old or broken one.

Having now described my invention,what I claim as new, and desire tosecure by Letters Patent, is

The combination with an axle-box lid having an inner recess Z? of aspring-socket D-having a fiat heel extension secured to the body of thelid below recess 1) and a hook-like recess extending from said heelextension over said recess toward the pivot of the lid.

NATHAN H. DAVIS.
